Iliac fossa
Iliac Fossa
The Iliac Fossa (pronounced: /ɪˈlaɪæk ˈfɒsə/) is a large, smooth, concave surface in the internal surface of the ilium, one of the three bones that make up the human hip bone.
Etymology
The term "Iliac Fossa" is derived from the Latin words "ilia" meaning flank or loin and "fossa" meaning ditch or trench.
Anatomy
The Iliac Fossa is bounded by the iliac crest superiorly, the arcuate line inferiorly, and the anterior and posterior gluteal lines laterally and medially, respectively. It serves as the attachment site for the iliacus muscle, which is part of the iliopsoas group responsible for hip flexion.
